ANTENNA ANALYZER ACROSS THE HF BAND, YOU WILL SEE SOME VARIATIONS IN THE
MEASURED VALUES OF RESISTANCE AND REACTANCE.  THAT IS WHY A LOW BAND SUCH

ENOUGH SPECTRUM YOU SHOULD GET AN IDEA OF WHAT THE MEASURED RESISTANCE
TENDS TO LEVEL OFF AT, SO YOU CAN IGNORE POSSIBLE FREQUENCY RELATED
ABERRATIONS.  IT SHOULD BE EASY AND OBVIOUS TO TELL WHETHER THE BALUN IS 1
1 OR 4 1.  YOU CAN FIND A VIDEO THAT SHOWS THIS MEASUREMENT PROCESS ON THE

CAN YOU HELP?  A IM VERY SORRY, I DONT HAVE A READY ANSWER FOR YOU.  BUT IF
THE UNIT IS SMOKING, UNPLUG IT AND LEAVE THE POWER OFF UNTIL YOU HAVE FOUND

RESTORERS OFTEN REPLACE ALL THE CAPACITORS WITH MODERN COMPONENTS AS THEIR
